Answer:
B. Nuclear fission reactions use only a small amount of material to
produce a large amount of energy.
C. Nuclear reactors use controlled reactions.
Explanation:
Nuclear reactors are devices that contain and control nuclear chain reactions while releasing heat produced from these nuclear chain reactions at a controlled rate.
A nuclear power plant uses the enormous amount of heat that are produced from the nuclear chain reactions occurring in the nuclear reactor to turn water into steam, which then drives turbine generators that generate electricity.
The nuclear chain reactions occurring in the nuclear reactor are fission chain reactions. A nuclear fission reaction is a reaction in which a larger atom is split into two or more smaller atoms when bombarded with energetic neutrons resulting in the release of large amounts of energy and more neutrons. The neutrons released split more atoms of the larger atom into smaller atoms in what is known as a chain reaction. This reaction is controlled by means of moderators. A moderator helps slow down the neutrons produced by fission to sustain the chain reaction.
Answer:
3.5 Molar
Explanation:
Molarity = no of moles/ volume of solution in liter
Molarity = 1.75/0.50
Molarity = 3.5 molar
D. Solute is the answer
Hope it's help
Explanation:
The answer is to this question is
60 m/s.
Answer:
Explanation:
Hello there!
In this case, according to the combustion of octane:
We can see there is a 2:25 mole ratio of octane to oxygen; therefore, we can calculate the moles of oxygen via the following stoichiometric factor:
